Hidrolisis Secara Enzimatis Protein Bungkil Biji Nyamplung (Calophyllum inophyllum) Menggunakan Bromelain
Full text linkNyamplung mengandung minyak yang cukup tinggi sehingga membuatnya potensial untuk digunakan sebagai bahan dasar pembuatan biofuel. Proses ekstraksi minyak dari biji nyamplung menghasilkan limbah padat dalam bentuk bungkil biji nyamplung yang masih memiliki kandungan protein dan belum optimal pemanfaatannya. Salah satu alternatif untuk mengolah protein dalam bungkil menjadi produk yang lebih bernilai adalah melalui hidrolisis secara enzimatis menggunakan bromelain. Bromelain adalah kelompok sistein endoprotease yang memiliki spesifisitas pemotongan yang cukup luas terhadap berbagai residu asam amino meliputi arginin, lisin, tirosin, dan fenilalanin sehingga aplikasi bromelain dalam hidrolisis protein bungkil biji nyamplung diharapkan dapat menghasilkan derajat hidrolisis (DH) yang tinggi. Penelitian ini bertujuan untuk menentukan kandungan protein dalam bungkil biji nyamplung, dan menentukan pengaruh konsentrasi enzim serta waktu hidrolisis terhadap DH hidrolisat protein. Metode penelitian terdiri dari 2 tahapan yaitu : 1) analisis proksimat bungkil biji nyamplung dan 2) analisis DH hidrolisat protein menggunakan bromelain dengan variasi konsentrasi enzim (2, 6 dan 10)% (b/v), waktu hidrolisis (0, 30, 60, 120, 180 dan 240) menit pada pH 7 dan temperatur 450C. Hasil menunjukkan bahwa peningkatan konsentrasi enzim sebesar 10% dengan aktivitas enzim yang terukur (27,04 U/gr substrat) menghasilkan DH tertinggi (6,43%) dengan waktu hidrolisis 240 menit
Sosialisasi Budidaya Microgreens Skala Rumah Tangga bagi Masyarakat di Kelurahan Pandeyan Yogyakarta
No full textMicrogreens have emerged as a new trend in urban farming due to more practice, efficiency, affordable, short periods of cultivation, and highly nutrition than other types of urban farming methods. The increase of physical development in Pandeyan, ??Yogyakarta due to the increase in population has caused a decrease in the area for plant cultivation. One of the solutions to overcome this problem is through the socialization of household-scale microgreens cultivation. Therefore, this socialization aimed to enhance the knowledge of the Pandeyan community regarding the definition of microgreens, types of plants that can be cultivated, benefits, stages of cultivation, and business opportunities. The socialization was delivered in the form of a webinar on Tuesday, 30th November 2021 using Zoom platform, with a total 32 of participants. This activity is divided into 3 stages: introduction, transfer of knowledge, and discussion. Based on the evaluation, this activity has succeeded in increasing the community's knowledge about microgreens, their benefits, and the stages of microgreens cultivation based on the high enthusiasm of the community during the discussion session
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
